SySIFe inauguration

The COSYS/SII team is proud to have welcomed many of its partners to the inauguration of SySIFe at the end of 2025, and wishes you all the best for 2026, which will see the launch of the first experiment using the SySIFe simulator.

Happy New Year 2026 to all.

Sysife Project ‘Railway Infrastructure Request System’

The project includes the design and mechanical construction of the loading system, the development of a high-performance control system to enable high adaptability to loading conditions and to take into account the inertia associated with movement. It is complemented by the acquisition of dynamic cylinders and hydraulic units adapted to the desired performance, as well as an acquisition system and associated sensors.
